Method for manufacturing multiscale-structured metal support for low-temperature thin-film solid oxide fuel cell, and metal support manufactured thereby

Abstract

Provided is a method for manufacturing a multiscale structured metal support for low-temperature thin-film solid oxide fuel cells and to a metal support manufactured thereby. The method includes (a) filling the pores on the surface of a porous metal support with a first metal powder having a relatively large particle size; (b) filling the pores on the surface of the porous metal support with a second metal powder having a relatively small particle size and pressing the surface; (c) heat-treating the porous metal support, whose surface pores are filled with the first and second metal powders, in a reducing atmosphere; and (d) filling the pores on the surface of the heat-treated porous metal support with a ceramic powder and heat-treating the resulting support in a reducing atmosphere. Through these processes, a multiscale structured metal support suitable for application in low-temperature thin-film solid oxide fuel cells can be fabricated.
